Bits of plastic shavings in the water lines is a pretty common occurance; USUALLY just removing the screen at the faucet end and cleaning that fixes it. Speakers wired wrong- welcome to the Concertone gripe forum! And, bubble on tire is a tire manufacturer's defect- not F.R.'s. Antenna misaligned- first time I've heard of that one; dealer can fix it under warranty, and chemical smell/odor....black tank sanitation issue, or construction material smell- (example formaldehide)???? If that- open up the windows and let the "new smell" wear off for a few nice days- it really helps. If it is the tank, there are several brands of chemical deodorizers- you'll have to choose what smells good to you.
Unfortunately, these and virtually ALL campers are assembled and built with many different manufacturer's appliances, and although they are pretty good generally, sometimes they need adjustments and/or repairing. This forum will help you with much of those things. Randy
